I was recently at an all-around outdoors store, and the proprietor told me that some people use spotting scopes...
I had asked if it would be possible to get an adapter that
would allow the attachment of a DSLR to a spotting scope, and he noted that there are some that allow the lens of the spotting scope to be removed, and the camera to be mounted directly to it. Obviously, any shots taken with this set up would be from a tripod unless an extremely fast shutter speed is used, but wouldn't the magnification mean the sensor would be getting a limited amount of light except in extremely bright daylight? I also saw a nice set of 15x binoculars there for about 119... but I don't need those... So anyway, all this got me thinking; would it be possible to adapt half of a binocular using an adapter ring to an SLR, etc? Binoculars are rather cheap (and so are spotting scopes) in comparison to higher end zoom lenses. Any thoughts on this? |

Binoculars are rather cheap (and so are spotting scopes) in comparison to higher end zoom lenses. Any thoughts on this? Can be done, but you have to still think "aperture". Divide the focal-length of the main objective lens by its diameter. You'll find you're using really small apertures. Research "digi-scoping" or "digiscoping". I found that any superzoom camera with a high-quality telextender on it, or even stacked telextenders, to provide 3-5 more stops aperture with much less effort and hassle (adapters, tripod, cumbersome optics tube, etc.) while providing just as good if not much better image quality. Take for example this image someone posted once, using two stacked 1.7x telextenders on a handheld (no tripod used) older superzoom camera. Shooting with a 35mm equivalent focal-length (EFL) of 1248mm at f3.5. http://farm4.static.flickr.com/3141/3060429818_b01dbdb8ac_o.jpg The OP explaining another 1.7x digital-zoom was used to take advantage of the little extra resolution you can get from upsampling direct from the sensor in-camera. Giving the image, and real world performance, of a 2,122mm EFL lens at f/3.5. You'd be hard pressed to even find any telescope optics that could accomplish that, let alone a spotting scope or binoculars. Many newer superzoom cameras with their even greater focal-lengths, when used along with high-quality telextenders, could go far beyond that. A combination that can all fit in one windbreaker pocket. |

Binoculars are rather cheap (and so are spotting scopes) in comparison to higher end zoom lenses. Any thoughts on this? I don't see why not. I do a lot of photomicrography, and one of my adapters is simply the appropriate T-ring at one end (Canon EOS in my case). The rest is a simple aluminum barrel, with two sets of three nylon screws each, which attach the adapter to the microscope eyepiece. I attach the adapter instead of a lens and use the microscope as the lens. This adapter has no glass in it, but simply uses the microscope's glass. Once attached, I focus through the camera's viewfinder. I have other more expensive adapters that include their own lenses, but you get a more restricted field of view with them. If you had a similar adapter that could fit the ocular lens of one side of a binocular, I don't see why it wouldn't work. |

As I recall, the lamented Spiratone had lots of adapters for that sort of thing--but that was then and this is now. I miss some of those old mail order places like Spiratone and Edmund Scientific.
